The ARCTIC MX-4 is a premium-grade thermal paste with exceptional performance and ease of application. It is an electrically non-conductive paste that is applied between CPU / GPU and designated coolers to transfer the dissipated heat from the components to the heat sink. Since the ARCTIC MX-4 is a metal-free compound, it eliminates the risks of causing short circuit and in turn adding more protection to your computer.The new formula in the ARCTIC MX-4 features optimal thermal conductivity and low thermal resistance. These characteristics effectively dissipate the emitted heat from the core components.The consistency of the ARCTIC MX-4 is designed for simple application. Its texture is just thin enough to spread onto components using fingers without creating much mess.
